IIRC, in shell, only function can call return.

Not needed (default behavior).

Avoid the negative logic please.

> +LIBIIO_CONF_OPTS += -DENABLE_IPV6=OFF

We usually prefer having symetrical options, so either add:
---
else
LIBIIO_CONF_OPTS += -DENABLE_IPV6=ON
---

or use the one-liner form (only if there is no other vars. to set):
LIBIIO_CONF_OPTS += -DENABLE_IPV6=$(if $(BR2_INET_IPV6),ON,OFF)
